Progesterone as Luteal Support in Frozen IVF Natural Cycles

Summary

The ProFET study aims to investigate if luteal phase support by vaginal progesterone, is superior to no luteal phase support, in terms of live birth rate per woman after a frozen embryo transfer (FET), in a natural cycle (NC) after in-vitro fertilization (IVF), and if 7 weeks of treatment is superior to 3 weeks duration.
